But my laptop doesnt seem to depend. acer-wmi doesn't rely on the instance_id, it just gets ignored. It does use the method_id though. > Is this > instance and method_id a WMI standart or is it a HP and Acer laptop > specific? My laptop is a LG. Yes, these are part of the WMI standard (in that, they need to be passed in). I would recommend you read through the spec: http://web.archive.org/web/20071011004327/http://www.microsoft.com/whdc/system/pnppwr/wmi/wmi-acpi.mspx Essentially - you need to pass the instance and method id's, but what values you pass and their meaning is completely vendor specific (which is pretty much a good summary of ACPI-WMI in general). -Carlos -- E-Mail: carlos@xxxxxxxxxxxxxxxxxxx Web: strangeworlds.co.uk GPG Key ID: 0x23EE722D -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
